Need assistance programming a Motorola Radio and setting up my Repeater at Home Hampton VA

[LEO757]

I'm a retired law enforcement officer and although not new to two way radios, I am new to GMRS, and will be using the system we recently purchased for camping and power outages mostly. The rig is a Motorola XPR 4350, a "silver box" with two lines in and 8 lines out to the repeater and and an SVR 250 UHF repeater. It is likely pretty powerful so I'm told. Looking for a local expert who can help to program the radio to 8 GMRS channels and get the repeater up & running here in Fox Hill. I also have a (25 watt?) Motorola Radius mobile/base with 8 each GMRS and repeater channels, and want to learn how to get it up and running.  With this radio I have a home roof mounted 4 foot fiberglass UHF antenna.

Any advice or assistance with getting these things off the ground would be appreciated. I also have 3 Motorola M1225 VHF small form factor mobile radios that I would like to get rid of.

Feel free to email me. highway@dr.com

Specs say it's a 2 watt output.

So very confused. You mention a XPR and also a SVR. I assume someone used the SVR for the RX side of the repeater and the XPR is being used as the TX ? Can you snap a picture. While that would work normally the SVR would be a different band than the XPR in the LMR world. Lots of them in service for vehicle extenders per say. Anyway if you can give us more info it would help. The XPR and the SVR use totally different software so you'll need software and cables for both. SVR may be a bit harder to find but its out there.

That is how I would do it - use the XPR as the transmitter and the SVR as the receiver - make sure both are programmed only to one channel so no one can veer them off-course and where a duplexer isn't tuned.

Did the same with a Motorola XTL5000 and Futurecom DVRS as a "camping repeater" and works well for the most part - but definitely keep duty cycle low on the repeater or the transmit radio WILL get hot.
